Fifty years after the assassination of Dr. Martin Luther King, Jr., SiriusXM honors his life and legacy with special programming.

Radio Andy (Ch. 102) host Dan Rather shared memories of covering the iconic activist during the early days of the Civil Rights Movement and the “emotional earthquake” felt by Americans when the news of his assassination broke.

P.O.T.U.S. (Ch. 124) commemorated the anniversary by featuring excerpts of King’s historic Mountaintop speech, as well as remarks from Robert Kennedy and President Lyndon B. Johnson. From there, coverage focused on MLK’s legacy and featured clips from historical experts, politicians including Rep. John Lewis and Sen. Fred Harris, and modern-day pundits and journalists.

Progress (Ch. 127) returned to Memphis, Tenn. for the official ceremony at the Lorraine Motel, the site of Dr. King’s assassination. Mark Thompson spoke with activists and civil rights leaders about their memories and reflections, 50 years later.
